Discovery
Rui didn't immediately head to the dungeon, he had something important to do. He immediately whipped out a letter before writing down some instructions about banning certain third parties from transacting with Esosale Suppliers.
He painstakingly wrote down all the names that he memorized from the document that Commissioner Reze provided, regretting that he didn't ask for a copy. He considered Guildmaster Bradt's perspective on the matter. He knew that the man would definitely have thoughts on the new directive that Rui provided.
There was no way he wouldn't notice that the restricted companies were from the Kandrian Empire. This would instantly tell him that Rui at the very least had something to do with the Kandrian Empire.
